Research And Implementation Of Agent Based Distributed Information System Supporting Environment For Integration And Evolution

The rapid development of information technology makes a lot of information system expose to the open network environment. With information systems’ overall scale expanding along with the expansion of the amount of Internet big data. At the same time,Internet creates more and more big information system,and these systems’ topology gradually diversify and isomerization, so the information flow between information systems is becoming more inefficient and difficult under the traditional pattern. Therefore, how to effectively solve the problem of information island and information dissymmetry, and giving full play to the advantages of distributed information system to realize data sharing and collaboration by the Unified management platform and data acquisition platform.With the develpentment of distributed computing and artificial intelligence, Agent theory and Multi-Agent System with its intelligent node and flexible system structure have brought a new of thought for information system integration.This paper puts forward an Agent based distributed information system supporting environment for integration evolution, using Agent technology to implement the data exchange and cooperation between the information system through integrating information systems to an unified distributed environment. The environment map the integrated systems of information system into the nodes of Agent of Multi-Agent System. Through the Agent model and public based service, to realize the data flowing between information systems, and improve the adaptability of the single integrated unit and the ability of dynamic reconfiguration of the integrated units.This paper puts forward an evolution model of information system integration by introducing the main problems of the distributed information system integration and the characteristics of the Multi-Agent System, and expounds how the supporting environment solves the problems of system integration and evolution, including the nunbers of Agent integrated and public service.Based on the design, this paper gives the implementation of the supporting environment and designs an air defense simulation system to verifiy the effectiveness of the supporting environment by experimental analysis.
